stops 48, 48'serving on each to lock them in position. The splines 47, 47 on columns l5, 15 fit in corresponding ways in slides 45, and hold said slides against rotation on said columns 15 and 15. The head l6 has -mounted thereon'the cope 5O which-is pivoted for horizontal movement thereon and the head 46 has mounted thereon the match part 52 of a pattern which is pivoted for At the upper end of each of slides 45, 45 is formed a hook 5a which is adaptedto cooperate with the hook 56 which is pivoted to a ring 58 mounted on each of said columns 15,.15 near the top thereof. A cam 60 and a handle 62 therefor I ,sei've toengageand disengage hook 54 from hook 56 when desired. A match part 64 for matching part52 ispositioned onthe table 66 of press lQ'andfa drag 68 is mounted on 7 table 66'.

In'the use andoperation of the above der scribed machine aoope mold and a drag mold are,formed either-by jolting or squeezing in a manner well known in the art in the cope 50 and the drag 68, respectively. After the -two parts of the mold are. made the cope 50 is separated from the match part 64; and the matchpart 52 is separated from drag 68, the tables 66, 66' and-the hooks 54:,

- 56 being used respectively to raise and-suspend the parts. The columns 15,15 on cap 12-are rotated about column 4 to bring cope 50 and the scope moldftherein over the drag 68.; The table 66' is, then raised to bring the pins 70, 70 of'drag'68 into engagement withvcorresponding holes in flanges 72, 72 on cope 50.and to bring drag 68 against cope 2 50. The handles 7 5, 7 5' on the cope moldretaining slides not shown but vknown in the wart and, particularly'described in} my copending application Serial Number 63,605,

vfiled May 29, 1925,; are movedtoi release the cope mold whereupon the table 66 is I loweredto bring the drag and drag mold down and to bringwith them the cope: mold.

. A coverv such as is known in the art may then be positioned overthe cope moldand zsecuredto the flask'and the unit removed a for the pouring of metal into the mold. The

cope ,50is then returned to its position over table 66. I

If a cover forjthe cope mold and drag -mold together is us'ed'then the cope and draw a when brought together are secured to veac other, the cope mold retaining slides released through handles 75 Y75 and the table'66.

The cover is then put on and secured to the 3 bottom board and removed from themachine. r

The cope is then hung by hooks54, 56 and the cope and drag released from each, the drag and pattern plate, lowered by the table and the pattern plate removed. The drag is then raised into engagement with thecope and the cope mold released by means' flof handles 7 5, 7 5 and eitherthe cope'orboth the cope and drag are removed from the finished mold in the manner above deseribed.
